Abstract Electrochemical nitrate reduction (NO 3 − RR) is being recognized as a sustainable approach to synthesizing ammonia which essential for the chemical industry and key agricultural input conventionally produced through hard‐to‐abate Haber Bosch process. Among various transition metals, copper‐based electrocatalysts stand out in efficaciously carrying this reaction owing their superior electrocatalytic activity selectivity. In context, here, current state of research advanced scientific understandings employing Copper NO₃ RR are succinctly, but comprehensively, presented while focusing on its design strategies enhance performance. First, NO mechanisms taking place at surface copper described, followed by discussion unique attributes facilitating electrosynthesis. Then, electrocatalyst fabrication routes designing reviewed, emphasizing role evolved structure, morphology, textural properties chemistries improving kinetics. Nanostructuring, facet defect engineering, support, doping, alloying, heterojunction single active catalysts (SACs) centers parameters enhanced behavior highlighted.

Abstract Electrochemical conversion of CO 2 and NO 3 − to high value‐added urea is a win–win strategy for both resources the environment. However, yield rate selectivity are still low. In this work, Cu metals grafted into interlayers an imine‐linked covalent organic framework (COF) form stable Cu─In dual metal sites by strong coordination hydroxyl O imine N atoms in framework. It found that optimal CuIn 1.07 ‐COF electrocatalyst exhibits impressive 2924.4 µg h −1 mg Faradaic efficiency (FE) 54.7% H‐cell, which surpasses most previously reported catalysts electrosynthesis. situ spectroscopy theoretical calculations reveal due stronger electronic interaction between In, * NH intermediate generated on site from reduction, then couples with neighbor produce lower energy barrier, effectively promotes electrochemical co‐reduction urea.

Biocement is a promising alternative to conventional cement, offering advantages in sustainability and reducing carbon footprints. However, its widespread adoption has been hindered by the relatively high production costs. This review aims explore various strategies advancements biocement that can contribute cost reduction. Specifically, we discuss selection of low-cost microbial growth media for microbially induced carbonate precipitation (MICP), utilization plant extractives as enzyme substitutes enzyme-induced (EICP), substitution urea with urine source nitrogen, exploration affordable alternatives calcium ions, valorization ammonia/ammonium byproducts, other pathways. The these could significantly enhance biocement's scalability sustainability, paving way more eco-friendly cost-effective construction practices.
